Update packages, ensuring native_stack_traces is bumped to 0.7.0. - #192473

Recent changes to Dart to remove the VM isolate also updated package/native_stack_traces to handle this change. Without those changes, using flutter symbolize fails with newer snapshots. This PR updates the Flutter package dependencies, including a bump of native_stack_traces from 0.6.1 to 0.7.0.

Fixes: #191879
